To all whom t may concern.'

Be it known tha'tI, IVILLIAM T. GUTH, a citizen of the United States,and a resident of the city of New York, lfiorough of Brook- Anotherobject of the invention is to pro vide a lavatory with a grooved orinclined surface arranged `in such a manner that ,p water may bedirected thereover for producing a cle-an and flushing sheet of waterfor the entire bowl.

A still further- Object of the invention is to provide a self-cleaning'lavatory whereby upon the turning of a single spigot, water isdischarged in several directions and automatically converted into asheet as it moves into the bowl proper. i

Referring to the accompanying drawing by numerals, 11 indicates awashstand or lavatory provided-with a suitable back 12 and a bowl 13.VIn forming the lavatory, the bowl 13 merges into a fiat section 14 whichis slightly inclined as indicated in Figures 2 and 3 so that water mayfreely flow therefrom into the bowl 13. The fiat section 14 alsopreferably merges intothe back 12 as indicated in Figure 3 so that theparts will be an integral structure. i

In order to iiush the bowl or clean the same, a specially constructeddistributing member 15 is provided which is connected with the valve 16.A suitable supply pipe 17 is connected with the valve 1G so that whenthe valve 16 is turned on, water will be discharged into thedistributing member 15 and from thence forced over the fiat section 14Vas indicated by the arrows in Figure 1. It will be noted that thedistributing member 15 is a tubular structure and merges into the casing0f the valve 16, said tubular structure being Open at both ends andprovided with a slot 18 extending the full length thereof so that asheet of water will be discharged directly toward the bowl 13 and inaddition a stream of wat-er will be forced in the opposite directionover the fiat Vsection 14. 4The water passing over the fiat section 14will gravitate over the bowl by reason of the inclined arrangement andin addition by reason of the fact that the inclined section 14 isgradually reduced until it reaches the point 19. The point 19 is adividing structure which causes the water to be discharged atthis pointinto the bowl.

In Figures 4 to 8 inclusive, will be seen a modified structure to thatillustrated in Figures 1 to 3. In this forni of the invention thelavatory 11 is provided with a flat section 20 preferably horizontal anda substantially annular recess or notch 21 which is divided by the point19. In this form of the invention the water is supplied to the valve 15through a. pipe 22 connected with pipes 23 and 24 which in turn areconnected with the hot and cold water pipes 25 and 26. In this way warmwater is discharged through the valve 15 when the same is turned on. Thecasing' of this valve is preferably formed integral with a projection 27which` merges into a tubular distributing member 28. said distributingmember being open at both ends and provided with a slot 29 adjacent thebottom. The distributing member 2S fits into the groove or depression21. as illustrated in Figures 4 and 6 so that when the valve 15 isturned on some Of the water will be discharged directly downwardly byreason of the slot 29 while the remaining water will be dischargedlaterally in oppositevdirections along the groove or depression 2l asindicated by the arrows in Figure el. This water will overflow into thebowl 13 and thereby thoroughly flushV each end and a slit facing thebowl and exand clean the bowl. l

After anyone uses the bowl, thesame may be readily cleaned by turning onthe valve l5 which will quickly flush the bowl and `clean the samewithout any further effort on the part of the person operating thevalve. If the bowl is flushed after each time it is used it will remainclean whereas if it is used and some of the soiled water is leftstanding, it will be necessary to use soap and otherrmeans for cleaning,which operation is entirely obviated by the complete flushing of allparts of the bowl and the surface 14.

Vhat I claim is l. A self-cleaning lavatory comprising a bowl formedwith a flat platform surrounding the bowl adjacent its top and slightlyinclined toward the same, said platform adjacent the front of the bowlpresenting a restrictedarea to impede the flow of water V around theplatform and compel the same to flow into the bowl all around its walls;

i and means for releasing the water on said platform.

Y 2. A self-cleaning lavatory comprising a bowl formed with a flatplatform surroundingthe bowl adjacent it top and slightly inclinedtoward the same, said platform v adjacent the front of the bowlpresenting a restricted area to impede the flow of water around theplatform and compel the same point substantially circumferentially ofthebowl for an appreciable distance, said tubular member having a discharge`opening at tending from one end to the other, and a valve member forturning on and off water to said tubular member. Y

3. In a self-cleaning lavatory, the combination with Va bowl formed witha substantially flat platform surrouiidingthe bowl at the top, of a tubeextending along the rear edge of said flat platform for an appreciabledistance and presenting open ends, and a slit extending between saidends, said slit facing the platform to permit the water emitted fromsaid tube to form a running film of water around the edges of the bowl.

4. A self-cleaning lavatory of the character described, comprising abowl formedV at yits top with a substantially annular recess tubularmember. Y Y Y WILLIAM T. GUTl-l.
